Nvidia Graphics Driver Update for macOS 10.13.2 build 17C89
If you have macOS 10.13.2 build 17C89 (from Combo Update), there's a new web driver v378.10.10.10.25.103. (Still not seen a download page for it yet as of Dec. 22nd.) To check your macOS build number, select Apple menu -> "About this Mac", and click on the macOS version number.
(This driver was posted after the CUDA 387.99 release (below), but saw a post it worked with .103.)

macOS CUDA driver version format change
- The macOS CUDA driver version now uses the format xxx.xx compare to x.x.x to be consistent with our Linux and Windows driver version namin convention.

Supported macOS - 10.13.x

An alternative method to download the latest CUDA driver is within macOS environment. Access the latest driver through System Preferences > Other > CUDA. Click 'Install CUDA Update'. Supports all NVIDIA products available on Mac HW. "

Here's a direct download link for CUDA 387.99. I later saw a post that the .103 driver (for 10.13.2 build 17C89) was supported by CUDA 387.99. (The previous CUDA 9.x versions were reported to work in macOS 10.12.6, despite not listing it on the download page. Curious if this version does as well, but not able to test that personally.)

As of post time, the CUDA link on the download page goes to the current CUDA version, which doesn't list macOS 10.12.x support, but a reader report on Nov. 1st said he used it with the previous build of macOS 10.12.6 and nvidia web driver. (Unknown if new CUDA 387.99 works in Sierra, as its download page also only lists macOS 10.13.x support.)

The driver page mentions an old CUDA v7.5.29, but link goes to the current version, which doesn't list OS X 10.11.x support. If you already have CUDA installed, check the prefs for an update. (The last CUDA version that listed OS X 10.11.x support on the download page was CUDA 8.0.90, but the D/L page listing isn't always accurate.)

(Apple used to include Safari fixes in OS updates, but the article doesn't mention it.)

FYI on Nvidia Web Driver Updates:
Users of Nvidia's web drivers should know that new OS updates (versions or later build numbers after Security Updates) break any currently installed Nvidia web graphics driver. I'd switch to the default Apple driver and reboot before updating, if your card is supported with the default drivers. If not, wait for a Nvidia driver update. (Some non-Mac EFI cards are not supported by default OS X drivers.)
Of course have a current backup (and if possible, a Clone) of your boot drive before any update. (Update - see above for Nvidia CUDA 387.99 and web graphics driver updates for macOS 10.13.2 and new builds of 10.12.6 and 10.11.6.)
